Comment Chong Chen:
- "With an average shell length of 300mm and a staggering record size of 380mm, the aptly named "Goliath Conch" is the largest strombid species alive today. A herbivorous gastropod living in shallow water down to about -50m deep, it is found mostly on sandy bottoms and primarily feeds on algae and seagrass. Although generally considered to be endemic to Brazil, recent findings reported the presence of two small populations in Barbados as well, presumably recently settled through a rare dispersal event. Its handsome shell is distinctively adorned with a very extensively flared outer lip and thin layer of golden brown periostracum. During recent years it has been moved around a few genera as part of the extensive revision of the family Strombidae, including Strombus, Eustrombus, Titanostrombus, before finally settling in Lobatus, its current genus. Though a locally common species in Brazil, it is not easy to acquire a large and operculated specimen with a perfect, unfiled lip."
